With the advent of personalized medicine, and recognition of the high degree of biological variability in human pathobiology, it is important to understand the comparative value of a single biomarker/diagnostic versus a panel versus a profile. In addition, the growth of Preventive Medicine has spurred the development of "Wellness" in individual patients, and the necessity for understanding and measuring the transition from a state of health (wellness) to ultimately a state of full blown disease onset. This complex process occurs via a multitude of biological pathways and networks and manifests at a biochemical and clinical systems level.
